Cl. 106--5 6 Claims ABSTRACT OF THE DISCLOSURE A spray shoe polish that is wax and silicone free. Ethyl cellulose is used as a base. A plasticizer and an inhibiter are employed as are three solvents having different boiling points for providing high gloss, no wax build-up, solubility of previous coatings, crack inhibition and dispersal of previously applied wax.

REFERENCE TO RELATED APPLICATION This application is a continuation-in-part of the application of Milton Nevitt, Ser. No. 189,398, filed Oct. 14, 1971, now Pat. No. 3,704,143, for Aerosol Spray Polish.

BACKGROUND OF THE INVENTION Field of the invention This invention relates to a wax-free and silicone-free polishing composition of the aerosol type especially adapted to be sprayed on shoes for both shining and polishing shoes and effectively waterproofing the lasts thereof.

Description of the prior art In the past aerosol spray shoe polishes containing waxes such as carnauba wax :and/ or silicones have been used. These polishes have had undersirable results from continued use because of wax build-up which causes an uneven and unslightly surface, and because heretofore the use of silicones has caused cracking of the leather of the last of the shoe on which it is sprayed. Further, in the case of shoe polishes it has been generally necessary to utilize a pigment as a part of the mixture to gain an effective and pleasing shine for shoes, which pigment requires spraying only in a protected or special area decreasing the desirability of the aerosol product due to possibility of staining. Further, when a pigmented product is utilized the shoe polish is adapted for use only on shoes of one specific color.

In the past, also various anti-blotching agents such as sodium dodecylbenzene sulfonate in a solution which must be wiped off to give a reasonable gloss or buffed to provide a shine.

SUMMARY OF THE INVENTION The present invention overcomes the disadvantage of the prior shoe polish by using in combination with ethylcellulose and diethyl phthalate as a plasticizer, a combina tion of three solvents of different boiling points which serve to assure an exceedingly high gloss with great depth and clarity and which employs a solvent inhibiter for inhibiting the cracking of the shoe leather, which leaves no wax build-up and which, in fact, smoothes out and utilizes any pigmented wax coating already on the shoe leather to re-pigment and color scuffed portions of the shoe.

3,782,979 Patented Jan. 1, 1974 Ice DETAILED DESCRIPTION OF THE INVENTION The base used is preferably ethyl cellulose. Various other lacquer bases such as nitro cellulose have been tried but these bases have a tendency to color and stain rugs, carpets or clothing adjacent the shoes to be shined if such material is sprayed thereon. When using ethyl cellulose as a base, it will remain suitably plastic for at least the reasonable life of the shoes when as a plasticizer, diethyl phthalate is also employed. Other plasticizers have been tried but none eliminated the cracking of leather as well in the combination as did diethyl phthlate.

Besides the base and plasticizer, three solvents are used in the aerosol spray shoe polish to gain the desired results of this invention. As a base solvent, the substance sold under the trade name Cellulose Acetate which is ethylene glycol monoacetate is employed. As a solvent fully compatible with the thyl cellulose, alcohol, such as ethanol is employed which in the combination claimed immediately dissolves, spreads, disperses and evens out any carnauba wax or the like which remains on the shoes from previous polishings and fills in pits, cracks and scuffs with this material.

As an ultra-fast acting solvent of very low boiling point which will at least partially dissolve prior lacquer coatings of most types which had been sprayed on the shoe to be polished there is used methylene chloride. This quickly evaporating solvent has been found to be useful in that almost immediately after spraying the uppermost layer of molecules evaporate leaving a sufliciently hard coating so the wearer may immediately utilize the shoes Without fear of smudging the finish.

As the solvent inhibitor for preventing cracking of the shoe leather by slight lubrication of the surface of the shoe leather Cloroethene (111 Tricloroethane) is employed. Perfume may be employed as desired.

In the example of the composition of this invention the following materials were co-mixed and packaged in an aerosol container at pressures ranging between 30 and 60 p.s.i.
